Attach sketches to new planes (Redefine)

For design reasons, you may need to attach a sketch to a different sketch plane than the one on which it originated.

In a part of assembly file, right-click an existing sketch in the browser and choose Redefine. Move the sketch to a planar face or work plane , then use constraints and dimensions to position it and modify its size, as needed.

The following design solutions use Redefine:

• You want to move a sketch from one planar face or work plane to another one to reorient a feature on your part.
• You want to delete a feature but opt to retain its sketch. You redefine the sketch on a new face or work plane, and then use it to create a feature.
• You edited a feature, and the face on which the sketch originated no longer exists (such as changing an extrusion to a cut). You redefine the sketch on a new plane or face, change or add dimensions, and then use it to create a feature.
• You want to specify a different planar face or work plane upon which the sketch resides (is dependent). It can be useful in cases where the sketch must be relocated. However, another use for the command is to repair a sketch that has become sick. It can happen when a feature with dependent sketches and features is deleted, but the dependent sketches and features are retained. Such retained sketches and features enter the sick state. An alert symbol is placed next to the affected sketch and feature entries in the browser. Use Redefine to re-associate the sketch to another planar face or work plane in the assembly.

Procedures

Attach a sketch to a different plane (Redefine)

Use Redefine in a part or an assembly file to move an existing sketch to a different planar face or work plane than the one on which it originated, and then use constraints and dimensions to position it and modify its size as needed.

1. In the browser, select the sketch you want to attach to a face or plane.
2. Right-click and select Redefine.
3. Click the face or plane on which to attach the sketch.

If the sketch is constrained or dimensioned to the plane on which it originated, the constrained geometry is included when the sketch is moved to a different plane. You can delete extraneous geometry as needed.
